We do this with e clips as well. We buy from McMaster.
It's actually quite easy, and we use a cheapo old Grizzly lathe with just 3 speeds and a lot of broken ares to do it.
Using a 0.040" wide grooving tool and a 1" dial indicator, you can get pretty good precision on these parts. 7075 is not that hard to turn a tiny groove in from my experience. We've never milled solid blocks or anything.
